+ <description>
+ <p>Multiple vulnerabilities have been discovered in libgcrypt. Please
+ review the CVE identifiers referenced below for details.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>Side-channel attacks can leak private key information. A separate
+ critical bug allows an attacker who obtains 4640 bits from the RNG to
+ trivially predict the next 160 bits of output.
+ </p>
+
+ </impact>
+ <workaround>
+ <p>There is no known workaround at this time.</p>
+ </workaround>
+ <resolution>
+ <p>All libgcrypt users should upgrade to the latest version:</p>
